Kurzfassung

Discontinuous system modeling is a present topic when working with practical models of technical systems. Numerical algorithms can only handle models with a given structure of the discontinuity effects. In the paper we show some examples that motivate the investigation of extended problem classes. The sensitivity analysis of all the systems
gives important information about the dependency of the model solution on model parameters like controller parameters. We discuss models with nonsmooth switching functions and models with several switching functions influencing the model dynamics at the same time.
